To help, you’ll have to master the same techniques scientists use to find and characterize exoplanets – worlds orbiting faraway stars.

Using NASA's exoplanet-hunting spacecraft, the Transiting Exoplanet Survey Satellite (TESS), scientists have spotted a record-breaking triple-star system so tightly bound that it could fit ...

"We have no way to determine how different exoplanets really look in detail yet, and this makes them a rich space for creativity." As shocking as it sounds today, prior to the 1990s, scientists ...

A few decades ago, astronomers were just entering a new frontier of exoplanet discovery. Exoplanets are planets located outside our solar system. They orbit distant stars and represent mysterious ...

For centuries, planets beyond our solar system—called exoplanets—existed only in theory and science fiction. It seemed nearly impossible to detect planets light-years away, since the ...

Data from the massive telescope also suggests the exoplanet, the name for a planet outside the solar system, may also have a surface covered in water and an atmosphere rich with hydrogen.

Studying the chemical cloud has taken a long time because it is often obscured by WASP-49 b (left) and the exoplanet's home star WASP-49 (right). (Image credit: NASA/JPL-Caltech) In addition to ...

With the discovery of planets beyond our solar system 25 years ago, exoplanet research has expanded dramatically, with new state-of-the-art ground-based and space-based missions dedicated to their ...

And that’s exactly what scientists have been doing for decades: searching for exoplanets, worlds orbiting faraway stars. They’ve had tremendous success: So far, NASA’s official count of ...
